DETAILED DESCRIPTION

In order to enable those skilled in the art to understand the technical solutions of the present disclosure, reference will be made clearly and completely technical solutions in the embodiments of the present disclosure with accompanying drawings.

It should be noted that the terms “at least one of A and B” and “A and/or B” in the specification and claims of the present disclosure may be interchangeable, which means A, or B, or both A and B. It should be noted that terms “first” and “second” in the specification and claims of the present disclosure and the accompanying drawings are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that data used in such a manner may be interchanged under appropriate circumstances so that embodiments of the present disclosure described herein may be implemented in a sequence other than the sequence illustrated or described herein. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present disclosure; instead, the implementations described in the following exemplary embodiments are merely examples of an apparatus and method consistent with the attached claims and some aspects of the present disclosure.

With the continuous development of Internet technology, various electronic games used to enrich the entertainment life of users have also been continuously developed. In order to increase the player's gaming experience, some background music is usually set for the game.

For example, in some rhythm games, different background music is usually designed for different game scenes. In view of the variety of game scenes, and each background music is played in a single thread, when multiple background music needs to be switched in a more complex game scene, it is often necessary to store multiple music in the video game in advance. Will cause the storage space occupied by video games to be larger.

As an example, in related technologies, in order to increase the game experience of the player, the player often uses music with a more intense rhythm when transaction scenes, and often uses some music with a slower rhythm when the player ends the battle. In this way, it is necessary to store at least two pieces of music in the video game in advance, one with a more intense rhythm and the other with a slow rhythm, which will cause multiple music to be pre-stored in the video game. The storage space occupied is relatively large.

To this end, the present disclosure provides a method for audio generation and apparatus, a server, and a storage medium to at least solve the problem of electronic games occupying relatively large storage space in the related art.

In the following, taking a rhythm game in a music type as a target game as an example, a method for audio generation provided by an embodiment of the present disclosure is introduced. The method for audio generation provided by the embodiments of the present disclosure not only can play different background music in different game scenes, but also try to avoid the problem of electronic games occupying a large storage space. In the method, a target rhythm (known as Beat) corresponding to a target game scene, and a target verse melody (known as Main) and a target chorus melody (known as Repeat) corresponding to the target game scene and/or behavior state data of a player character may be first obtained, and the target rhythm is configured as a first audio track, the target verse melody is configured as a second audio track, and the target chorus melody is configured as a third audio track, and finally start playing time of the first audio track, the second audio track and the third audio track are aligned to beat occurrence times of a first beat, a second beat and a third beat in first metronome data respectively, to generate the target audio.

Since the target audio includes three different audio tracks, when the target audio is played, the purpose of playing different background music can be achieved only by playing the audio of different audio tracks, so the present disclosure only needs one target audio to achieve playing multiple pieces of background music without pre-storing the multiple pieces of music, thereby making the storage space occupied by the electronic game smaller.

The method for audio generation provided by the present disclosure will be described in detail below with reference to FIG. 1 to FIG. 6.

As shown in FIG. 1, FIG. 1 is a schematic flowchart of a method for audio generation according to an exemplary embodiment. The method for audio generation includes steps 110 to 130, which are specifically described as follows. The steps of the method may be executed by a device for audio generation, the device may be provided as a server.

First, in 110, a target rhythm, a target verse melody, and a target chorus melody are obtained.

The target rhythm corresponds to the target game scene, and the target verse melody and the target chorus melody correspond to the target game scene and/or data of behavior state of the player character respectively.

In some embodiments of the present disclosure, the target rhythm is the audio that is played from the beginning of the game scene to the end after entering the game scene. For example, the target rhythm may be a set of drums played in a loop, which may be used to remind the player of the music rhythm in the game scene, so that the player can operate based on the music rhythm.

The target verse melody may start playing when the game scene is in progress, and stop playing when the playing duration reaches a preset duration. The preset duration may be a duration before the player enters a combat behavior state. The target chorus melody may be played in a loop until the game scene ends or the game scene is exited after the target verse melody ends.

It should be noted that the foregoing description of the playback sequence between the target verse melody and the target chorus melody is only an exemplary expression, and the present disclosure does not impose any limitation on it.

In some embodiments of the present disclosure, the target game scene may be a transaction scene, a casual scene, a chat scene, and so on. Each target game scene corresponds to a target rhythm, where multiple game scenes may share a target rhythm. For example, both the casual scene and the chat scene correspond to target rhythm A, and the transaction scene corresponds to target rhythm B.

Similarly, the transaction scene may correspond to the target verse melody A and the target chorus melody A, the casual scene corresponds to the target verse melody A and the target chorus melody B, and the chat scene corresponds to the target verse melody C and the target chorus melody B, etc.

In addition, the target verse melody and target chorus melody corresponding to the data of behavior state of the player character may also be obtained. The data of behavior state of the player character may be a combat behavior state of the player character, an exploration behavior state of the player character, and so on. For example, the combat behavior state of the player character corresponds to the target verse melody A and the target chorus melody A, and the exploration behavior state of the player character corresponds to the target verse melody A and the target chorus melody B.

Next, in 120, the target rhythm is configured as a first audio track, the target verse melody is configured as a second audio track, and the target chorus melody is configured as a third audio track.

The first audio track, the second audio track, and the third audio track are different.

In some embodiments of the present disclosure, it may be as shown in FIG. 2, which is a schematic diagram showing an audio track configuration according to an exemplary embodiment. As shown in FIG. 2, the target rhythm is configured as the first audio track 21; the target verse melody is configured as the second audio track 22; and the target chorus melody is configured as the third audio track 23.

Next, in 130, a target audio is generated by aligning start playing time of the first audio track, the second audio track and the third audio track to beat occurrence times of a first beat, a second beat and a third beat in first metronome data respectively.

The first metronome data includes a first offset, and the occurrence time of each beat in the first metronome data is determined based on the first reference time and the first offset.

In some embodiments of the present disclosure, during the opening process of the game, the Lua 5.1 development language can be used to establish metronome data in the Unity game engine. The reference time may be the system time of the client terminal of the target game. For example, the first offset included in the first metronome data is 0.5 seconds, and if the system time (reference time) of the client of the target game is 10:00, then the occurrence times of the beats can be sequentially determined as 10:00:05, 10:01:00, 10:01:05 and so on.

The above-mentioned specific implementations of step 110 and step 130 will be described in detail below through specific examples.

In the embodiment of the present disclosure, the target rhythm corresponding to the target game scene and the target verse melody and target chorus melody corresponding to the target game scene and/or the data of behavior state of the player character are first acquired, and then the target rhythm and target verse melody and the target chorus melody are configured as different audio tracks, and the first, second, and third audio tracks are obtained; finally, start playing time of the first audio track, the second audio track and the third audio track are aligned to beat occurrence times of a first beat, a second beat and a third beat in first metronome data respectively, to generate the target audio.

Since the target audio includes three different audio tracks, when the target audio is played, it is only necessary to play different audio tracks to achieve the purpose of playing different background music. Therefore, the present disclosure only needs one target audio to achieve playing of background music without storing multiple pieces of music in advance, thereby making the storage space occupied by the electronic game smaller.

The above step 110 is introduced below through FIG. 3 and specific examples.

In some embodiments of the present disclosure, in order to increase the richness of background music, it is also possible to generate different background music every time the player plays the same game scene. Please refer to FIG. 3 for details.

As shown in FIG. 3, FIG. 3 is a schematic flowchart of a method for audio generation based on acquiring rhythm and melody according to an exemplary embodiment. In some embodiments of the present disclosure, the step 110 may further include the following steps:

In 1101, a second rhythm corresponding to the target game scene is determined from a preset first rhythm based on a first correspondence and the target game scene, and the target rhythm is obtained in the second rhythm.

The first rhythm includes at least one second rhythm; the first correspondence is the correspondence between the game scene and the rhythm data.

In 1103, a second verse melody corresponding to the target game scene is determined from a preset first verse melody based on a second correspondence and the target game scene and/or the data of behavior state of the player character, and the target verse melody is obtained in the second verse melody.

The first verse melody includes at least one second verse melody; the second correspondence is the correspondence between a verse melody and at least one of a game scene and/or a data of behavior state of the player character.

In 1105, a second chorus melody corresponding to the target game scene is determined from a preset first chorus melody based on a third correspondence and the target game scene and/or the data of behavior state of the player character, and the target chorus melody is obtained in the second chorus melody.

The first chorus melody includes at least one second chorus melody; the third correspondence is the correspondence between a chorus melody and at least one of the game scene and the data of behavior state of the player character.

Taking the target rhythm, the target verse melody, and the target chorus melody all corresponding to the target game scene as an example, the above steps 1101 to 1105 are described in detail.

First, the first rhythm, the first verse melody and the first chorus melody can be preset for the game scene of the electronic game. The first rhythm includes the second rhythm corresponding to the game scene, the first verse melody includes the second verse melody corresponding to the game scene, and the first chorus melody includes the second chorus melody corresponding to the game scene.

For example, the game scene includes a transaction scene and a casual scene. The preset first rhythm includes a second rhythm A corresponding to the transaction scene and a second rhythm B corresponding to the casual scene; the first verse melody includes a second verse melody A corresponding to the transaction scene and a second verse melody B corresponding to the casual scene; the first chorus melody includes the second chorus melody A corresponding to the transaction scene and the second chorus melody B corresponding to the casual scene.

In this way, when acquiring the target rhythm, if the target game scene is a transaction scene, a second rhythm corresponding to the transaction scene may be determined from the first rhythm as the second rhythm A, and in this way, the target rhythm may be obtained randomly from multiple rhythms in the second rhythm A.

Similarly, if the target game scene is a transaction scene, when the target verse melody is obtained, the second verse melody corresponding to the transaction scene is determined from the first verse melody as the second verse melody A, then the target verse melody may be obtained randomly from multiple verse melodies in the second verse melody A.

If the target game scene is a transaction scene, when acquiring the target chorus melody, the second chorus melody corresponding to the transaction scene may be determined from the first chorus melody as the second chorus melody A, and the target chorus melody may be obtained randomly from the multiple chorus melodies in the second chorus melody A.

Since in the above embodiment, the target rhythm, target verse melody, and target chorus melody are randomly obtained from the second rhythm, the second verse melody, and the second chorus melody corresponding to the target game scene each time, so that the different background music can be generated for player when the same game scene is played each time, which making the background music richer.

In some embodiments of the present disclosure, since the player character may appear in the transaction scene to trigger the player character's combat behavior state, but after the player character's combat behavior state ends, the player character still does not exit the transaction scene, but continues to perform an exploratory behavior in the transaction scene (such as picking up the battle reward in the transaction scene after the battle is over).

At this time, in order to make the background music also have changes in playback, it is possible to correspond the target verse melody and target chorus melody with the data of behavior state of the player character, so that the background music can be changed with the behavior state of the player character.

In the following, the target rhythm corresponds to the target game scene, the target verse melody and the target chorus melody correspond to the player character, and the above steps 1101 to 1105 are described in detail.

First, the first rhythm may be preset for the game scene of the electronic game, and the first verse melody and the first chorus melody may be set for the behavior state of the player character in the electronic game. The first rhythm includes the second rhythm corresponding to the game scene, the first verse melody includes the second verse melody corresponding to the behavior state of the player character, and the first chorus melody includes the second chorus melody corresponding to the behavior state of the player character.

For example, the game scene includes a transaction scene and a casual scene, and the behavior state of a player character includes a combat behavior state and an exploration behavior state.

In this way, the preset first rhythm includes the second rhythm A corresponding to the transaction scene and the second rhythm B corresponding to the casual scene; the first verse melody includes the second verse melody A corresponding to the combat behavior state and the second verse melody B corresponding to the exploration behavior state; the first chorus melody includes the second chorus melody A corresponding to the combat behavior state and the second chorus melody B corresponding to the exploration behavior state.

In this way, when acquiring the target rhythm, if the target game scene is a transaction scene, the second rhythm corresponding to the transaction scene is determined from the first rhythm as the second rhythm A, and then the target rhythm may be randomly obtained from multiple rhythms in the second rhythm A.

Similarly, if the behavior state of the player character at this time is the combat behavior state, when acquiring the target verse melody, the second verse melody corresponding to the combat behavior state is determined from the first verse melody as the second verse melody A, in this way, the target verse melody is randomly obtained from multiple verse melodies in the second verse melody A.

If the behavior state of the player character at this time is the combat behavior state, when obtaining the target chorus melody, the second chorus melody corresponding to the combat behavior state can be determined from the first chorus melody as the second chorus melody A. In this way, the target chorus melody may be randomly acquired from multiple chorus melodies in the second chorus melody A.

Because in the above embodiment, the target rhythm is randomly obtained in the second rhythm corresponding to the target game scene, and the target verse melody and the target chorus melody are obtained from the second verse melody and the second chorus melody corresponding to the data of behavior state of the player character, such that different background music may be generated when the player plays the same game scene, and the background music is different under the behavior of different player characters, which makes the generated background music richer.

In some other embodiments of the present disclosure, the rhythm corresponding to each game scene, the verse melody and the chorus melody corresponding to each game scene and/or the behavior state of the player character may also be preset.

Thus, when acquiring the target rhythm, the target verse melody and the target chorus melody, the rhythm corresponding to the target game scene in the preset rhythm is the target rhythm, and the verse melody and the chorus melody corresponding to the target game scene and/or the data of behavior state of the player character in the preset verse melody and chorus melody are the target verse melody and the target chorus melody. Thus, the target rhythm can be directly obtained from the preset rhythm, the target verse melody is obtained from the preset verse melody, and the target chorus melody is obtained from the preset chorus melody. In this way, the background music corresponding to the same game scene and/or the same player character's data of behavior state can be made the same, making the background music of the entire electronic game more concise.

In some embodiments of the present disclosure, the first beat in the first metronome data may include at least one sub beat, the second beat may include at least one sub beat, and the third beat may include at least one sub beat. The first audio track obtained through step 120 may include at least one rhythm segment, for example, two measures may be used as one rhythm segment; the second audio track obtained through step 120 may include at least one verse melody segment, for example, two measures or four measures are used as a verse melody segment; the third track obtained through step 120 may include at least one chorus melody segment, for example, two measures or four measures can be used as a chorus melody segment.

In this way, in some embodiments of the present disclosure, in order to prevent the generated target audio from incorrect beats, it is also necessary to set the start playing time of the first audio track, the second audio track, and the third audio track to be aligned with the beat occurrence times of the first beat, the second beat, and third beat in the metronome data. The above step 130 will be described in detail below with reference to FIG. 4 and FIG. 5 respectively.

In some embodiments of the present disclosure, as shown in FIG. 4, FIG. 4 is a schematic flowchart of a method for audio generation based on beat alignment according to an exemplary embodiment.

As shown in FIG. 4, step 130 may further include the following steps.

In 1301, the start playing time of each rhythm segment in the first audio track is aligned with the occurrence time of each sub-beat in the first beat.

In 1303, the start playing time of each verse melody segment in the second audio track is aligned with the occurrence time of each sub-beat in the second beat.

In 1305, the start playing time of each chorus melody segment in the third track is aligned with the occurrence time of each sub-beat in the third beat.

In 1307, the target audio is generated based on the aligned first audio track, second audio track, and third audio track.

As an example, the first audio track includes at least one rhythm segment, each rhythm segment may be aligned with the beat occurrence time in the metronome every time it is played. For example, the first audio track includes a rhythm segment A and a rhythm segment B. The length of the rhythm segment A is 10 s. If the 100th second after the start of the game scene is the playing time of the rhythm segment A, at the 100th second, the rhythm segment A is aligned with the occurrence time of the beat in the first beat. Then, at the 110th second, the rhythm segment B is aligned with the occurrence time of the beat in the first beat again.

At this time, it should be noted that as long as the rhythm segment A and the rhythm segment B start to play at the time of the beat in the metronome at the same time, as to which beat the rhythm segment A and the rhythm segment B correspond to, there is no limitation here. The alignment method of the second audio track and the third audio track is the same as the alignment method of the first audio track, and will not be repeated here.

In other embodiments of the present disclosure, as shown in FIG. 5, FIG. 5 is a schematic flowchart of a method for audio generation based on beat alignment according to another exemplary embodiment.

As shown in FIG. 5, step 130 may further include the following steps.

In 1302, the start rhythm segment in the first audio track is aligned with the beat occurrence time of the start sub-beat in the first beat.

In 1304, the start verse melody segment in the second audio track is aligned with the beat occurrence time of the start sub-beat in the second beat.

In 1306, the start chorus melody segment in the third audio track is aligned with the beat occurrence time of the start sub-beat in the third beat.

In 1308, the target audio is generated based on the aligned first audio track, second audio track, and third audio track.

As an example, since the multiple segments included in each audio are played continuously, when the first, second, and third audio tracks are played, only the start segment of each audio is required to be aligned with the occurrence time of the beat in the first metronome.

Taking the first track including the rhythm segment A and the rhythm segment B (where the rhythm segment A occurs before the rhythm segment B, and the rhythm segment A is the starting rhythm segment) as an example, when playing the first track, it is only needed to change the start playing time of rhythm segment A to be aligned with the occurrence time of the start sub-beat in the first beat in the metronome, and the rhythm segment B will continue to be played cyclically after the playing of the rhythm segment A ends. For example, if the length of rhythm segment A is 10 seconds, the 100th second after the start of the game scene is the playing time of rhythm segment A, then at the 100th second, it is only needed to align the rhythm segment A with the occurrence time of the beat in the first beat. After the rhythm segment A is played at the 110th second, the rhythm segment B is continued to be played, without aligning start playing time of the rhythm segment B with the time when the beat occurrence time. Moreover, it should be noted that as long as the rhythm segment A starts to be played at the same time as the occurrence time of the beat in the metronome, as to which beat the rhythm segment A corresponds to, there is no limitation here. The alignment method of the second audio track and the third audio track is the same as the alignment method of the first audio track, which will not be repeated here.

In the embodiments of the present disclosure, the target audio is generated by aligning the start playing time of the first, second, and third audio tracks with the first, second, and third beats in the first metronome data, such that the generated target audio corresponds to the beat occurrence time of the metronome during playback, so as to prevent the target audio from incorrect beats during playback, so that the target audio has a better sense of rhythm.

In addition, considering that in the process of playing the target audio, there may be a situation where there may be a jam between the audio tracks due to hardware equipment or network reasons, so in some other embodiments of the present disclosure, during the playback of the target audio, the actual playback times of the first audio track, the second audio track, and the third audio track in the target audio are detected. For more details, please refer to FIG. 6.

FIG. 6 is a schematic flowchart of a method for audio generation according to another exemplary embodiment. As shown in FIG. 6, the method includes step 610 to step 650.

In 610, the target rhythm, the target verse melody, and the target chorus melody are obtained.

The target rhythm corresponds to the target game scene, and the target verse melody and the target chorus melody correspond to the target game scene and/or the data of behavior state of the player character respectively.

In 620, the target rhythm is configured as the first audio track, the target verse melody is configured as the second audio track, and the target chorus melody is configured as the third audio track.

The first audio track, the second audio track, and the third audio track are different.

In 630, the target audio is generated by aligning the start playing time of the first, second, and third audio tracks with the first, second, and third beat occurrence times in the first metronome data.

The first metronome data includes a first offset, and the occurrence time of each beat in the first metronome data is determined based on the first reference time and the first offset.

The above steps 610 to 630 are the same steps as the steps 110 to 130 shown in FIG. 1, which will not be repeated here.

In 640, during the playback of the target audio, the actual playing time of the first audio track, the second audio track, and the third audio track in the target audio are obtained respectively.

In the embodiments of the present disclosure, since the first audio track, the second audio track, and the third audio track in the target audio are on different audio tracks, when the target audio is played, the first audio track, the second audio track, and the third track will be played separately, without interfering with each other. Thus, when the target audio is played, the actual playing time of the first audio track, the second audio track, and the third audio track can be obtained.

In 650, in a case that a difference between the actual playing time of the first audio track, the second audio track, or the third audio track and its aligned beat occurrence time is greater than a preset threshold, the first reference time in the first metronome data is adjusted to the actual playing time, and the occurrence time of the target beat is adjusted based on the adjusted first reference time and the first offset.

The target beat is the beat that occurs after the actual playing time in the first metronome data.

In some embodiments of the present disclosure, if the first offset included in the first metronome data is 1 s and the reference time is 10:00:00, then the beat occurrence time of each beat in the first metronome should be 10:00:01, 10:00:02, 10:00:03, 10:00:04 and so on.

Taking the first audio track and the preset threshold being 0.1 s as an example, if the first audio track should be aligned with the beat occurrence time 10:00:02, but the actual playback time is 10:00:02:05, then it is known that the difference between the actual playback time of the first audio track and the aligned beat occurrence time is 0.5 s, which is greater than the preset threshold of 0.1 s. In this way, it can be understood that the audio playback is stuck at this time.

Therefore, for the next playback, the first track can be aligned with the beat occurrence time in the first metronome. At this time, the first reference time corresponding to the first metronome can be adjusted from 10:00:00 to 10:02:05, and then the target beat that originally needed to occur after 10:02:05 may be adjusted. That is, because the first reference time is adjusted from 10:00:00 to 10:02:05, the beat occurrence time of the target beat that originally needed to occur at 10:00:03 and 10:00:04 will be adjusted to 10:03:05 and 10:04:05 respectively based on the adjusted first reference time 10:02:05 and the first offset ls. In this way, next, the played first audio track may be aligned with the beat occurrence time in the first metronome again, so that when the target audio is played, it is possible to avoid the occurrence of wrong beats as much as possible.

In some embodiments of the present disclosure, in the Unity game engine, the playback progress of the audio track is measured by directly using the audio source time or the audio source time samples to play the track, so as to obtain accurate playback time. In addition, audio source play scheduled may be used to ensure that the music accurately falls on the beat.

In other embodiments of the present disclosure, the rhythm of the background music can also be adjusted based on the data of behavior state of the player. Specifically, after step 130, the method can further include the following steps: obtaining the first target data of behavior state of the player character; adjusting the first offset based on the first target data of behavior state and the fourth correspondence, in which the fourth correspondence is the correspondence between the data of behavior state of the player and the offset.

As an example, the first target data of behavior state may be the current behavior state of the player character, and the fourth correspondence may include: the combat behavior state corresponds to the offset A, the exploratory behavior state corresponds to the offset B, and so on. The shorter the offset, the tighter the rhythm.

In this way, after acquiring the first target data of behavior state of the player character, the beat speed can be adjusted based on the behavior state of the player character, so that the rhythm of the background music can be changed with the behavior state of the player character. In addition, after adjusting the offset, it is still necessary to align the start playing time of the first, second, and third audio tracks with the occurrence time of the beat, so as to avoid wrong beats of the generated target audio as much as possible.

In other embodiments of the present disclosure, in order to be able to play specific background music based on the game scene and the data of behavior state of the player when the background music is played, so in other embodiments of the present disclosure, after step 130, The method may also include the following steps: during the playback of the target audio, obtaining a second target data of behavior state of the player character and game scene; in a case that the game scene is the target game scene and the second target data of behavior state meets the preset state, switching playing the target rhythm and the target chorus melody to playing the target rhythm and the verse melody.

In some embodiments of the present disclosure, the preset state may be an end combat behavior state, or an end exploration state, and so on.

In some game scenarios, the player character can trigger the player character's combat behavior state in the transaction scene, but after the player character's combat behavior state ends, the player character still does not exit the transaction scene, but continues to perform the exploration behavior in the transaction scene (for example, after the combat is over, picking up the battle reward in the transaction scene).

At this point, in order to be able to play the background music with a more intense rhythm in the transaction scene of the player character, and after the player character has not exited the transaction scene but ended the combat behavior state, the background music with a slower rhythm can be played. Therefore, during the playback of the target audio, the second target data of behavior state of the player character and the game scene are obtained.

The second target data of behavior state may be the current data of behavior state of the player character, and the acquired game scene may be the game scene where the player character is currently located.

If it is judged that the acquired game scene is still the target game scene (transaction scene), it indicates that the current player character has not exited or changed the game scene. At this time, it can be further judged whether the player character's second target data of behavior state meets the preset state (end combat state).

Next, after judging that the second target data of behavior state of the player character has met the preset state (i.e., the player character is in the end combat state), playing the target chorus melody in the target audio can be switched to playing the target verse melody.

For example, please continue to refer to FIG. 2, when the target audio is played, the target rhythm will start to play when entering the game scene and continue to play until the end of the game scene; when the player character enters the game scene but does not trigger the combat behavior state, the target verse melody may be played. Once the player character triggers the combat behavior state, the playback of the target verse melody may be ended and the target chorus melody is started to be played.

At this time, if the acquired second target data of behavior state of the player character satisfies the preset state (the end combat state), and the player character is still in the transaction scene, so, in order to make the background music corresponding to the behavior state of the player character, at this time, the volume of the target chorus melody originally played on the third track can be muted, so that the target chorus melody on the third track does not emit sound, and the target verse melody is invoked to be played to switch playing the target chorus melody to playing the verse melody.

In addition, it is also possible to directly pause the target chorus melody and directly invoke the target verse melody to play.

In the embodiments of the present disclosure, by pre-setting the preset state and acquiring the second target data of behavior state of the player character and game scene, even if the player character does not change the game scene, the playback of the target chorus melody may be switched to playing the verse melody in a case that the corresponding second target data of behavior state meets the present state, such that the background music playback can change with the behavior state of the player character, and there is no need to pre-store multiple music files, and only one target audio is needed to play different background music in different states, thus making the storage space occupied by electronic games smaller.

In some other embodiments of the present disclosure, the player may also upload background music by himself, and the electronic game may adjust the target object in the target game scene to perform actions based on the music uploaded by the player himself. Specifically, after step 130, the method may also include: receiving an uploaded music; identifying the second beat data corresponding to the music; controlling the target object in the target game scene to execute the target action based on the occurrence time of each beat in the second beat data.

The second beat data includes a second offset, and the occurrence time of each beat in the second metronome data is determined based on the second reference time and the second offset.

In some embodiments of the present disclosure, the target object may be at least one of a non-game character, a game scene, and a game special effect. Game characters can be player characters or non-player characters; game visual effects can be light and shadow effects in the game, player character skill effects, waterfalls in the scene, fallen leaves, etc.; game scene elements may be decorations used to decorate the game scene in the game scene, such as lanterns, trees, kites, etc.

As an example, the player can upload music by himself. After receiving the uploaded music, the apparatus for audio generation can identify the second metronome data corresponding to the uploaded music through algorithms such as music melody extraction (Audio Finger printer). The second metronome data includes a second offset, and the occurrence time of each beat in the second metronome data is determined based on the second reference time and the second offset.

In this way, after the second metronome data is identified, at least one of the non-game character, the game scene, and the game special effects in the target game scene can be controlled to execute the target action based on the occurrence time of each beat in the second beat data.

In the embodiment of the present disclosure, by identifying the second beat data corresponding to the uploaded music and controlling the target object in the target game scene, the target action can be executed based on the occurrence time of each beat in the second beat data, thereby making the background music of the electronic game can be adjusted autonomously based on the player's preferences, and the electronic game controls the target object in the target game scene to execute the target action based on the time when the second metronome data of the uploaded music occurs. It can also make the action of the target object in the target game scene adapting to the beat, making the target game scene more rhythmic.

It should be noted that the execution subject of the control method provided by the above-mentioned embodiments of the present disclosure may be a device for audio generation, or a module for audio generation in the device for audio generation for executing the method for audio generation.
